Highly efficient down‐conversion phosphors are demonstrated in a microcavity down‐conversion white OLED. Using a down‐conversion phosphors film, part of the blue light emitted from the microcavity blue OLED is converted to yellow and red light, resulting in white light emission. The photograph shows the image of a working device.
